FLOEA INDICA.                                 179
2. C. Blumeanum (Miers in Taylor's Annals, ser. 2. vii. 87);
foliis crasse 'coriaceis ovalibus vel oblongis peltatis acuminatis vel obr
tusis basi truncatis vel subcordatis subtus niveo-tomentosis, capitulis
in axillis racemosis.—Cocciilus Blwneanus, Wall. Oat. 4971! enccluso
B partim.
HAS. Malaya: ad Penang et Singapur, Wall.!
Jbutex alte scandens. Caulei* dense lanato-tomentosi, infra lanam fusci, striati.
Folia 7-12 poll, longa, 3-6 lata, petiolo S-5-pollicari, supra atro-viridia, glabraj
lucida. Bacemi fulvo-tomeutosi, vaHdi, 8-4 poll, longi, pedunculis capitulorum fere
pollicaribus. Flores raasculi ut in C.fenestrato.
This species, so far as can be ascertained from thfc small number of specimens
which we have seen, seems very distinct from C.fenestratum, in the much more
rigid and more elongated leaves, which are always peltate, whereas those of C.fenes-
tratum are only so in young plants, In young plants of the Ceylon species, how-
ever, the leaves are elongated like those of C. Blumeanum. The character derived
from the inflorescence is perhaps not constant.
Tribus II. TINOSPORE./E.
Sepala 6. 2Jelala 6, sepalis minora, raring 0. Ovaria 3. Drupa
styli cicatrice subterminali vel fere basilari notatso. Putamen antice
planum vel excavatum vel processu interne munitum. Semen amplii-
tropum, rarius anatropum, alburmnosum. Embryo axilis. Radicula
supera, styli cicatricem spectans. Gotyledones lateraliter divaricatse,
tenues.
The genera which are associated in this tribe by means of the character of the
laterally divaricating cotyledons, form a very natural group; and, though they differ
from one another a good deal in the shape and structure of .the putamen and se*ed,
yet in these respects also a regular gradation may be traced from one genus to
another, and they are all nearer to one another than to the other tribes of the Order,
The style is, ii» many of the genera, almost terminal, even in the ripe fruit, but in
Anamirta it is nearly basal. The peculiar obliquity of the cotyledons, which sepa-
rate like the blades of a pair of scissors (sometimes overlapping a little at the edges
only), make the seed much broader than in the following tribes, in \vhich it is always
nearly cylindrical. In Aspidocarya the seed is quite ilat, but more frequently it ia
curved forwards round the internal process of the putamen, when it becomes ovoid
or globose, and excavated anteriorly. The ruminated albumen of Tinospora is pecu-
liar, but is not an indication of immediate affinity, as it is absent in those genera
nearest allied to Tinospora, and present in Tiliacora, which has no near relationship
with it.
There is in the llookcrian Herbarium a specimen of a jVIenispermaceoos plant in
fruit, which probably belongs to this tribe, but which is too imperfect to admit of
proper description. It was collected in Assam by Griffith., The drupe is more than
an inch long, much compressed, with & fleshy eiocarp and a thin bony putamen, very
slightly rugose externally, and with a broad, shallow, longitudinal furrow on the ven-
tral face. On the -inner surface of *'the same face, there is a groove extending from
the ba«e to near the apex, from which the seed is pendulous. The seed is marked
by a distinct rhaphe, running from, the hilum to (the opposite extremity j it is quite
flat, but, from the decayed state of the specimen, the presence of albumen and the
structure of the embryo cannot be determined. If the cotyledons be laterally diva-
ricated, this fruit will come near Aspidocarya, ag vcing with it in the absence uf
any internal process of the putamcn, aad in the an tropous seed, but tlUTciiiig in tin-
shape of the putameu.
